 VISION Active-IR shock sensors use a tiny infra-red emitter, receiver and suspended reflector to detect impact. Even the smallest movement of the reflector is sensed, and intelligent analysis of the movement eliminates false triggers.
Competing shock sensors that use piezo or suspended magnet detectors are often confused by jackhammers, loud trucks, motorcycles, and muffler-modified cars. In contrast, the 318-052 eliminates falsing without sacrificing sensitivity using a much more reliable IR movement detector -- sensitivity is user-adjustable, with adequate coverage of any vehicle from sub-compact cars to oversized vans and 4x4's.
